有线宽带业务发展对运营商IP承载网络演进的影响

Impact of wired broadband services development on operators' IP network evolution

随着有线宽带业务的发展,以视频为主的有线宽带业务对网络承载能力提出了新的要求。分析了有线宽带业务流量疏导对带宽和网络质量的需求,从多播技术应用,BRAS、CDN部署方式,骨干网架构演进等多个角度,提出了可行的网络演进方案。

With the development of wired broadband services, new requirements on the carrying ability of network was put forward by video-dominated services. The demand on bandwidth and network quality of wired broadband traffic grooming was analyzed, and a feasible network evolution solution were presented from the perspective of mul- ticast technology application, BRAS and CDN deployment, backbone network architecture evolution and other point of view.
